SPECIFICATION forming part of Letters Patent No. 322,991,6ated July 28, 1885.

Application filed June 23, 1884.

T0 at whom, it may concern.-

Be it known that I, FRANK L. SrowELL, a citizen of the United States, and a resident of New York, in the county of New York and State of New York,have invented a certain new and useful Improved Combined Instrument, of which the following is a specification.

My invention relates to an instrument which is intended for the use of persons engaged in writing, drawing, and similar employments at a desk.

The invention consists in a novel combination and arrangement of devices whereby several instruments are combined or included in one handle or holder, and a neat and convenicnt desk instrument is produced.

The accompanying-drawings illustrate the invention. Figure 1 represents one form in which the instrument may be constructed. Fig. 2 represents another form. Fig. 3 is a detail view.

A represents a handle of suitable shape and size to beconveniently held in the hand after the manner of holding a penknife or ordinary eraser. This handle may be made of wood, hard rubber, ivory, celluloid, or any other suitable material.

B represents a steel blade attached to the handle A in the usual or any suitable manner.

The portion of the blade nearest the handle, for a length of about an inch, (more orless,)is provided with a file-surface, (designated by the letter 0.) Next to this file-surface,on one edge of the blade, is a notch, D, in the shape of a crescent or sickle, and sharpened to a keen edge. From the notch to the point of the blade is a sharp edge, E, and the opposite edge,

G, is sharpened from the point of the blade to the end of the file-surface. The sharp edge G'may be used for pen-making or for general cutting purposes. The edge E is used as an. eraser. The notch D is used as a pencilsharpener, and the file-surface G is used for (No model.)

sharpening the lead of a pencil to a fine point when desired. Then the file G is not in use, it may be covered by a sheath, J, (see Fig. 3,) slipped over it, so as to prevent dropping of the lead-powder on the paper, and also to prevent soiling of the fingers when the instrument is used for cutting, sharpening, or erasing, and the entire blade and part of the handle may be covered, when not in use, by a sheath similarvto that used for an ordinary eraser. The handle A has its rear end provided with an indiarubber pencil-eraser. When made in the form shown in Fig. 1, the rubber K is made a part of the handle proper, and is. connected thereto by a metallic band or collar, L. When made in the form shown in Fig. 2, the rubber M is arranged to slide in and out of a tube formed in or attached to the rear end of the handle. In such case the rubber is provided with a knob or, stud, at, working in a slot, 8, provided with lateral notches t, so that the rubber may be protruded when needed and withdrawn when not in use.

WVhat I claim as new, and desire to secure by Letters Patent, is-

V 1. An instrument for desk purposes, consisting of a handle, A, provided with a doubleedged blade, 13, having a sharpening-notch formed in one edge only thereof, and a fiat oblong file-surface in the rear of said blade, substantially .as specified.

2. The handle A, provided with the blade 13, having the file-surface O, in combination with the sheath J, for protecting said file-surface, substantially as set forth.

Signed at New York, in the county of New York and State of New York, this 19th day of June, A. D. 1884.
